Title:
TARGET INFORMATION DETECTION SYSTEM AND TARGET INFORMATION DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/064835
Kind Code:
A1
Abstract:
In order to make it possible to separately detect a plurality of targets having the same speed using a narrow-band RF signal and BB signal by an inexpensive and easily designed means, the target information detection system according to the present invention includes a measurement-side speed detection device for detecting the speed of a measurement-side moving body as a moving body speed, and a target-side speed detection device for detecting the speed of a target as a target speed, and when it is determined from a Doppler frequency that the relative speed of the measurement-side moving body and the target is equal to or less than a mode switching speed set in advance, a target information detection device switches a target information detection mode from a Doppler mode to a communication mode, acquires a moving-body speed via the measurement-side speed detection device and acquires a target speed via the target-side speed detection device, and calculates target information using the moving-body speed and the target speed.
